“Late Friday night, we learned of an incident involving an artist and a security guard on site. Since then, we have been in contact with those involved and the authorities, as we work together to resolve the situation. As always, our top priority is to ensure the safety of everyone at the festival.”

Thanks for the support. We are both very shaken and I am pretty bruised up. But blessed to be alive in this world. Others aren't as lucky. X
